Answer:
Step-by-step explanation:
For this case we need to define some notation:
represent the remaining length of the candle in inches
represent the time in hours that have elapsed since the candle was lit.
For this case we assume that L and f are related so then we can write this like that: L is a function of t.
And for this case we have a constant rate given of:
And we know a initial condition
So then since we have a constant rate of change we can use a linear model given by:
Where m is given and we need to find b. If we use the initial condition we have this:
And solving for b we got:
So then our lineal model would be given by:

Answer:
Step-by-step explanation:
Given
Coins = 20
Value = $3.05
Required
Determine the equation that represent this
From the question, we have that
d = the number of dimes
q = the number of quarters
This implies that;
Also;
---------- Standard unit of conversion;
This implies that
Hence, the equations are:
6x[7+(15-8)]divided by 3=28 hope this helps
